Description

Air conditioning system for vehicle

Technical Field

The present invention relates to an air conditioning system for a vehicle, and more particularly, to an air conditioning system for a vehicle including an ionizer that prevents ions emitted when conditioned air is discharged into a vehicle interior from being extinguished.

Background

The interior (vehicle compartment) of a vehicle is narrow and sealed, and is easily contaminated, and particularly, air pollution of the vehicle compartment tends to be increased due to the influence of fine dust and various pollutants flowing into the vehicle compartment. When the air conditioner is driven in rainy or high humidity weather, bacteria and mold are propagated due to moisture condensed on the surface of the evaporator, and the bacteria and mold flow into the room, causing odor and various diseases.

In view of the above, there have been recently actively studied and developed air cleaners for vehicles for purifying indoor air of vehicles, and further, there is a tendency to directly mount an ionizer for solving the above-mentioned problems on existing air conditioners for vehicles.

Fig. 1 is a perspective view showing an air conditioner for a vehicle provided with a related art ionizer (ionizer).

An HVAC module 20 (Air Conditioning) for taking in and Conditioning the vehicle interior or the outdoor Air and discharging the Air is provided in the engine compartment of the vehicle, and an Air Conditioning duct module 40 shown in fig. 1 is connected to the HVAC module 20 so that the conditioned Air is discharged through a plurality of vent holes (not shown) provided in the vehicle interior.

Among them, as shown in fig. 1, the ionizer 50 is disposed inside the HVAC module 20, most of which is disposed at the evaporator 21 before air conditioning of air.

However, in the case of the vehicle air conditioner provided with the conventional ionizer 50 configured as described above, since the ions emitted from the ionizer 50 exhibit a metal orientation, most of the ions are extinguished while passing through the metallic evaporator 21, and the actual ionization efficiency is reduced.

Detailed Description

Hereinafter, a preferred embodiment of an air conditioning system for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a first conceptual view for explaining an optimal position provided at an air-conditioning duct module in the structure of the air-conditioning system of the vehicle of the present invention, fig. 3 is a schematic flow diagram of air-conditioning air for designing an optimal position of an ionizer in the structure of the air-conditioning system of the vehicle of the present invention, fig. 4 is a second conceptual view for explaining an optimal position provided at an air-conditioning duct module in the structure of the air-conditioning system of the vehicle of the present invention, and fig. 5 is a block diagram showing a control situation of a plurality of ionizers.

Referring to fig. 2 to 3, a preferred embodiment of an air conditioning system of a vehicle of the present invention includes: a vehicle Air Conditioning module (hereinafter, referred to as "HVAC module 120") disposed outside the vehicle compartment; an air-conditioning duct module 140 configured to communicate between the HVAC module 120 and a plurality of vents (not shown) (vents) provided at a plurality of positions of the vehicle compartment, thereby guiding air conditioned by the HVAC module 120 to the vehicle compartment; and a plurality of ionizers 150 disposed in the air-conditioning air flow path inside the air-conditioning duct module 140 to generate ions.

The HVAC module 120 is disposed in a nacelle of a vehicle and includes: an air conditioning case provided with an air conditioning space capable of sucking vehicle interior air or outdoor air and performing air conditioning; and an evaporator disposed inside the air conditioning case and configured to air-condition air inside the air conditioning case in accordance with a refrigeration cycle operation of the refrigerant.

The HVAC module 120 is connected to the air-conditioning duct module 140 shown in fig. 2 to flow air-conditioning air into the air-conditioning duct module 140, and a plurality of distal ends of the air-conditioning duct module 140 communicate with a plurality of vent holes provided at a plurality of positions in the vehicle interior, so that the air-conditioning air is discharged into the vehicle interior through the plurality of vent holes.

Referring to fig. 2 and 3, the air-conditioning duct module 140 may include: a left side duct 141 and a right side duct 141 for supplying conditioned air to a driver seat and a passenger seat in a vehicle cabin; left and right front leg ducts (not shown) for supplying air-conditioning air from below the driver's seat and the passenger seat toward the legs of the driver's seat occupant and the passenger seat occupant; a left rear foot duct and a right rear foot duct (not shown) for supplying air-conditioning air to the feet of occupants in rear seats of the vehicle interior; and a center console duct (not shown) for supplying air-conditioning air to occupants of rear seats of the vehicle interior.

In particular, referring to fig. 3, the left lateral duct 141 and the right lateral duct 141 may include: left and right extensions extending to the left or right from the HVAC module 120; the left discharge portion and the right discharge portion are bent backward from the left extension portion and the right extension portion and extend downward.

Wherein the ionizer 150 of the present invention is disposed inside the air-conditioning duct module 140, unlike the case where the ionizer is disposed inside the HVAC module 120, which has been described in the "background art" section, so as to minimize the situation where ions are extinguished.

In the structure of the air-conditioning duct module 140, the left side duct 141 and the right side duct 141 are locations where passengers frequently ride, and therefore, in order to minimize the situation where ions are extinguished, optimal location design of the ion generator 150 is particularly important.

As shown in fig. 2 (c), the ion generator 150 may be disposed in the left and right extending portions, which are one of the detailed structures of the left and

right side ducts

141 and 141, may be disposed inside the portions adjacent to the ends of the left and right discharge portions shown in fig. 2 (c), and may be disposed between the left and left discharge portions and between the right and right discharge portions shown in fig. 2 (c).

Compared to the ionizer 150 described in the "background art" section, the ionization efficiency can be also greatly improved only by disposing the ionizer 150 as described above inside the left-side duct 141 and the right-side duct 141.

However, in the interior of the left side duct 141 and the right side duct 141, it is required to individually design which position is set as the optimum position and the specific configuration of the ionizer 150 according to each set position.

For example, referring to fig. 3, when the ion generator 150 is disposed in the left and right extending portions of the left and

right side ducts

141 and 141, a Mixing region (Mixing Zone) by turbulent flow is formed inside the end portions of the left and right discharge portions that are bent rearward from the front ends of the left and right extending portions and extend downward, and therefore, a separate design of a specific structure of the ion generator 150 that can minimize the occurrence of the extinction of ions is required. Here, a detailed description will be given later when a specific structure of the ionizer 150 is explained.

In addition, referring to fig. 4, the ionizer 150 may be disposed at the left side duct 141(side duct), the right side duct 141(side duct), the left front leg duct (foot duct), the right front leg duct, the left rear leg duct, the right rear leg duct, and the center console duct (center conductor duct), respectively.

The ionizer 150 provided in the left side duct 141 functions to eliminate discomfort felt by the driver due to polluted air by using air-conditioned air directly blown to the passenger seated in the driver's seat as a fluid medium of ions, and the ionizer 150 provided in the right side duct 141 similarly discharges ions to the passenger seated in the passenger seat, thereby contributing to the passenger seat.

The ionizers 150 provided in the left and right front leg ducts are used for removing odor and the like generated in shoes and the like of a driver or a passenger in a passenger seat, and similarly, the ionizers 150 provided in the left and right rear leg ducts are used for a passenger in a rear seat.

The ion generator 150 provided in the center console duct can discharge ions to the rear seat occupant.

As described above, in a preferred embodiment of the air conditioning system for a vehicle according to the present invention, by separately providing the ion generator 150 in each duct connected to a plurality of ventilation holes provided in the vehicle interior, it is possible to minimize the destruction of ions generated by the driving of the ion generator 150 and to achieve air conditioning such as efficient deodorization for the entire vehicle interior.

Further, although not shown, air quality detection sensors capable of detecting the air quality of the vehicle interior may be provided at a plurality of positions of a portion where contamination of the vehicle interior is expected.

The plurality of ionizers 150 installed as described above can be controlled to operate individually based on the vehicle interior air quality data of the current state detected by the plurality of air quality detection sensors through the air quality detection at a plurality of positions of the vehicle interior, so that the HVAC module 120 and the ionizer 150 can be interlocked and the pollution source can be effectively removed according to the estimated position of the in-vehicle pollution gas.

For example, referring to fig. 5, a region set in the vehicle interior is set as a pollution Estimation region, and the region is divided into a plurality of regions, and the driving of the ion generator 150 belonging to which region is to be activated is determined by a pattern recognition method or a Bayesian Estimation method (Bayesian Estimation) based on the detected value of the air quality detection sensor and whether or not each of the plurality of vent holes connected to the air-conditioning duct module 140 is opened or closed, the amount of outside air blown into the interior of the vehicle by the HVAC module 120, whether or not the door window is opened or closed, and the traveling speed of the vehicle.

Fig. 6 and 7 are perspective views illustrating a first embodiment and a second embodiment of an ion generator in a configuration of an air conditioning system for a vehicle according to the present invention, fig. 8 is a schematic view illustrating installation of an ion plate in the configuration of the ion generator, fig. 9 is an exploded perspective view of the ion generator, fig. 10 is a partial sectional view taken along line a-a of fig. 8, and fig. 11 is a plan view illustrating upper and lower surfaces of the ion plate in the configuration of the ion generator.

In a preferred embodiment of the air conditioning system of the vehicle of the present invention, the plurality of ionizers may include

pattern electrodes

151, 152 imprinted (imparting) on the ion plate 161 as electrodes for generating ions.

By using

such pattern electrodes

151, 152 as electrodes for generating ions, a pulse control method can be introduced, which enables a miniaturized design of a transistor, thereby providing an advantage that miniaturization of a product can be achieved. In the control of the DC output mode such as the needle electrode or the carbon electrode in the related art, there is still a problem that miniaturization of the product is not easy due to a large size of the transistor.

Referring to fig. 6 to 9, the plurality of ionizers 150 may include: a lower case 160(lower case) fixed to the air-conditioning duct module 140 and having a predetermined space opened to one side; a shield cover 163(shield cover) that is tightly coupled to an inner wall surface inside the lower case 160; a printed circuit board 164 coupled to an inner space formed by the shield case 163; an ion plate 161(ion plate) coupled to an upper side of the shield case 163; an upper case 166(upper case) bonded in such a manner as to cover the ion plate.

Among them, the lower case 160 may be fixed at an inner circumferential surface inside the air-conditioning duct module 140 and formed to be opened toward a central portion where air-conditioning air flows.

The shield case 163 is formed to have a smaller volume than the lower case 160, and is closely attached to the inner surface of the lower case 160 except for the portion where the opening is formed, and a shield member 163 'performing the same function as the electromagnetic wave shielding part 161' of the ion plate 161 by plating described later may be formed on the inner surface of the shield case 163.

The printed circuit board 164 plays a role of transmitting and receiving an electrical signal applied from the

pattern electrodes

151, 152 of the ion plate 161 or applying a power source.

As described above, the ion plate 161 is configured to include the patterned

electrodes

151 and 152 formed by the embossing method, and thus it is possible to solve the problem that it is difficult to use a carbon brush type carbon electrode and a needle type needle electrode, which have a high ozone generation rate compared to the ion generation amount, as the electrode for the vehicle interior in the sealed space.

The ion plate 161 may have a + pole pattern 151 and a-pole pattern 152 stamped on an upper surface thereof, i.e., a surface facing the inside of the air-conditioning duct module 140, and an electromagnetic wave shielding part 161' made of the same material as the + pole pattern 151 and the-pole pattern 152 is plated on a lower surface thereof except for lower exposed portions of the + pole pattern 151 and the-pole pattern 152.

The electromagnetic wave shielding portion 161 'completely shields the printed circuit board 164 disposed inside the lower case 160 together with the shielding member 163' of the above-described shield case 163, thereby minimizing the influence of electromagnetic wave components such as electromagnetic waves generated in the printed circuit board 164 on the ionized ion configuration.

In a preferred embodiment of the air conditioning system of the vehicle of the present invention, instead of additionally providing an electromagnetic wave shielding plate, with reference to fig. 11, the same electromagnetic wave shielding effect is achieved by actively using the opposite surface of the ion plate 161 on which the + pole pattern part 151 and the-pole pattern part 152 are imprinted, so that it is possible to prevent an increase in the number of components and to achieve more effective performance.

In addition, referring to fig. 10, the ion plate 161 is configured such that its lower face is seated on the upper end edge of the shield case 163, and a part of the upper end edge end of the ion plate 161 is supported from the upper side to the lower side by a hook support portion formed on the upper end edge of the lower case 160.

At this time, the front end of the shielding member 163 'of the shield case 163 and the electromagnetic wave shielding part 161' formed on the opposite surface of the ion plate 161 have a contact point with each other, so that the electromagnetic wave shielding function can be completed only by the operation of providing the ion plate 161 at the upper end of the edge of the shield case 163.

Wherein, the ionizer 150 may further include: and a waterproof rubber frame 165 interposed between a hook support portion formed on the lower case 160, an upper end of the shield case 163, and an end portion of the ion plate 161.

By interposing the waterproof rubber frame 165 in the inner side edge portion of the lower case 160, intrusion of moisture such as condensed water due to the flow of air-conditioning air is prevented, and vibration generated from the air-conditioning duct module 140 due to the flow of air-conditioning air is absorbed, thereby playing a role of protecting structural members inside the lower case 160.

In addition, in a preferred embodiment of the air conditioning system of the vehicle of the present invention, the

pattern electrodes

151, 152 formed on the ion plate 161 of the ionizer 150, that is, the + pole pattern part 151 and the-pole pattern part 152, are preferably arranged in a perpendicular manner with respect to the flow direction of the air conditioning air flowing in the air conditioning duct module 140.

Referring to fig. 6 and 7, by dividing the + pole pattern part 151 and the-pole pattern part 152 in a direction perpendicular to the flow direction of the air-conditioning air, respectively, it is possible to minimize the opposite pole ions generated in the opposite poles from being mixed with each other and extinguished.

Referring to fig. 6, the ionizer 150 may be provided with a partition wall 153 of a predetermined height between the + pole pattern portion 151 and the-pole pattern portion 152.

The partition wall 153 also functions to prevent ions generated in each of the + pole pattern portion 151 and the-pole pattern portion 152 from being extinguished.

In the case of the ionizer 150 provided with the partition wall 153 as described above, it is preferable that the ionizer 150 be located in the Mixing Zone (Mixing Zone) described with reference to fig. 3 so that the generated ions are discharged through the plurality of vent holes in a state where the situation where the ions are extinguished is minimized.

Also, referring to fig. 7, the ion generator 150 may be configured by a separate ion plate 161 of a + pole ion plate 161a imprinted with a + pole pattern part 151 and a-pole ion plate 161b imprinted with a-pole pattern part 152, and the + pole ion plate 161a and the-pole ion plate 161b may be configured to be inclined such that surfaces on which the + pole pattern part 151 and the-pole pattern part 152 are formed, respectively, are along mutually opposing directions. That is, the + pole ion plate 161a and the-pole ion plate 161b may be arranged in an inclined manner such that the + pole ion plate 161a and the-pole ion plate 161b have a triangular cross section, and a portion where the + pole ion plate 161a and the-pole ion plate 161b adjoin each other forms the highest apex of the triangle.

The positive and

negative ion plates

161a and 161b arranged in an inclined manner in this case are also configured to minimize the extinction of ions generated in the positive and

negative pattern portions

151 and 152, similarly to the partition wall 153 described above.

In the case of the ion generator 150 provided with such inclined + and-

pole ion plates

161a and 161b, since the installation position thereof can be set inside the air-conditioning duct module 140 having a relatively high flow velocity, it is preferably provided inside the left and right extensions described with reference to fig. 3, since it has a substantially high effect of preventing ions from being extinguished.

A preferred embodiment of the air conditioning system for a vehicle of the present invention is described in detail above with reference to the accompanying drawings. However, the embodiment of the present invention is not limited to the preferred embodiment described above, and various modifications and equivalent implementations can be made by a person having ordinary skill in the art to which the present invention pertains.
